How about the new eight characters?

Any prediction technology can be developed to its accuracy. If you can't tell fortune, will so many people learn to predict? This obviously does not match. My aim is that it is customary for mules to come out for a walk and swear. If you want to know whether a forecasting system is accurate, you must learn from it before you can express your opinion. Now many people on the Internet curse people whose theories are different from their own. Indeed, this is not good.
